1 minute, 40 seconds. Just over a minute and a half.

43200 seconds / 60 seconds in a minute / 60 minutes in an hour = 12 otherwise known as half a day
60 seconds an 1 minute 60 minutes in 1 hour 30 minutes in half an hour 90 minutes in one and a half hours. So 90 minutes * 60 seconds = 5400 seconds
there are 12 seconds in a fifth of a minute
30 seconds in half a minute (there are 60 seconds in a minute)
90 seconds
108,030 seconds.
30 seconds is half a minute (0.5 minutes), as there are 60 seconds in a full minute.
30 seconds in 1/2 minute.
There are no minutes in half a minute. - In one minute there are 60 seconds. - In half a minute there are 30 seconds. - In one hour there are 60 minutes. - In half an hour there are 30 minutes.
30 seconds are one half minute. 60 seconds are one minute.
5400 seconds. ************************ 60 seconds = 1 minute 60 minutes = 1 hour so 1 and a half hours is 1.5x60x60= 5400 BUT I read question as 1 hour (60x60=3600seconds) plus half minute (0.5x60 = 30 seconds) so total is 3660 seconds
4.5hours*60minutes/hour*60seconds/minute = 1620 seconds
There are 60 seconds in a minute, so a half minute would be 30 seconds. If you have a length of time in half minutes, multiply that by 30 to get seconds. For example, 20 half minutes = 20 x 30 seconds = 600 seconds
1 minute, 40 seconds. Just over a minute and a half.
